the construction of tank cars, the sup orting structure includes two centerl sills yby t at are,

formed 'i of [angle iron' 'to provide outsetting flanges c,"an'd which center sills are spaced apart and are dis osed in the car structure in accordance wit the practice'that is now common in tank car construction. As Iwhave embodied my invention, the tank d is su ported at its ends by means of pillow bloc ts that are mounted upon the center sills and which permit movement of the tank with respect thereto longitudinally of the center` sills, vertical movement of the tank with respect to said pillow blocks being prevented by means of the usual tank bands f. ,The central portion of the tank has sliding mounting upon the to outsetting` flanges c of the center sills, w ich .mounting is desirablv secured by means of a edestal that inclu es feet g and which is esirably rigidly secured to the bottom of the tank, to which end it may have a curved rest h forming an inte ral part thereof and which is riveted to t e tank. The elements g and h are desirably formed in one casting. The feet g are provided with circular holes that snugly fit the shanks of the bolts i that are passed therethrough, the Shanks of these bolts also passing through holes la in the flanges c, which atter holes are elongated longitudinally of the center sills so as to permit some longitudinal movement of the feet g with respect to the center sills and thereby some longitudinal movement of the tank with respect to the tank supporting structure, the feet g referably sliding upon the center sills. The olts z' take part in preventing vertical displacement of the tank with respect to the center sills while permitting the described longitudinal movement of the tank, said bolts at the same time taking part in preventin rolling or lateral movement of the tanli.

By the structure thus far specificall described. the tank is centrally anchore( and is adapted to contract and expand, due to changes in temperature, between its ends and its anchorage, the pillow blocks upon which the tank is supported at its ends permitting such contraction and expansion.

The tank carries two depending fingers Z that are desirably formed in the same integral casting with the su port h and the feet g, these fingers being a ined longitudinally of the center sills and pro'ecting into the space between said sills. hese fingers are separated a distance longitudinally of the center sills that is suicient to permit the spring bufllnp;` mechanism to be interposed therebetween, this spring bufling mechanism including a follower plate or devices fm. that may be actuated by one finger, and a companion follower plate or devices n that may be actuated by the companion finger,

spring mechanism o being cooperatively relatedwith these follower plates, preferably, though not necessarily,` by being disposed longitinlinally of the center sills and therebetween, in which preferred arrangement the springs of the` spring mechanism themselves directly engage the follower' plates and, in copcration with the follower plates, the fingers Z and the cheeks 7) secured to lthe center sills preserve the tank in its normal position longitudinally of the center sills, but permit the tank to move longitudinally of the center sills when said sills encounter bumpingl or sudden pulling strains, the. airing mechanism restoring the tank with the aid of its copcrnting elements to the. `lroper normal position after the tank has )een moved longitudinally7 'from its normal position. Thus, for example, let it be assumed that the car is moving toward the right and that it has been suddenly checked in its movement. thon the tank (i, due to inertia, will tend to continue in its movement. whereupon the. left hand finger Z will move the rear follower plate m forward against the force of the springs o, thereby preventing excessive shearing strain upon the rivets that fasten the rest It and the tank togather, said springs thereafter disfending to return the rear follower plate to its initial position and thereby restore the tank to its normal position longitudinalil of the ccnter sills. If the car were trave ing in the rcverse direction and its speed were. suddenly checked, the right hand follower plate n would cooperate. with the finger l and the springs o in a reverse similar manner. lf tie Car were traveling` to the right and the speed were suddenly accelerated, the right hand finger and the right hand rollowal` plate n would cooperate with the springs 0 to permit of movement of the tank d to the left with respect to the center sills,y whereafter the springs o would normally reposition the tank. lf the car were movinpr to the, left and its speed were suddenly accelerated, the left hund finger l and the left hand follower plate m would cooperate with the springs o t0 permit of movement of the tank (l t0 the right with respect to the center sills, whereaftcr the springs 0 would normally reposition the tank. The cheek plates 7) thus constitute abutments against. which one or the other of the follower' plates is pressed by the spring mechanism in order to permit the desired longitudinal movement of the tank with respect to the center SillS. The apertures i.: are of such length and the springs o are of such capacity as both to be suited to the maximum sudden changes in speed which are expected in traflic. WhileY the cheek plates p are desirably mounted upon the inner opposing vertical faces of thel center sills in order to act as abutments for extending dovvnvvmdlvi from the-.car body said `:followerdevicesindependently of the smdbetween'lwhichthe follower devices are cent/er sills. 10 disposed, onev follower device bein movable In Witness whereof, I hereunto subscribe by one projection and the .other fo lower demy name this 17th day of June, A.
